Over at Titusonenine there is a discussion of some of the recent pleasant-sounding heresy from the Episcopal "bishop" of Utah, Ms. Carolyn Tanner Irish. One of the comments has pointed out that Ms. Irish was baptized in the Mormon faith, and never rebaptized.
One of the necessary ingredients for Holy Orders is that the candidate be a member of the one Church. To be a member of the one Church, one must be baptized. To be baptized into the one Church, the one baptizing must have the intention of baptizing you into the one Church. This intention is certainly lacking by those 'baptizing' in the Mormon faith. Ergo, etc. The Congregation on the Doctrine of the Faith reached this conclusion in 2001.
Not only is Ms. Irish ostensibly not a bishop, she is ostenbibly not even a Christian.
